Things to consider when buying the portable evaporative swamp coolers

The climate where you live in

Evaporative air colors work by drawing hot air from the outside and passes the air through a series of wet filter pads and humidifying it. The cooled, moist air is then exhausted inside the house or room where it is used.

Owners can connect the air cooler to a water supply to keep it filled with ice, or they can add ice manually as the supply runs low.

The key to making evaporative air coolers work best is in places with hot dry air – air that is almost similar to desert areas.

Evaporative coolers are actually ineffective in warm, humid environments because the air is already heavily saturated with moisture.

The type, size, and mobility

If you need cooling in different specific places at different times – choose standard sized coolers with casters to move them from space to space. There are also coolers that work best for personal cooling such as the lightweight ones.

If you just needed to cool down a bedroom, office or any single contained space, consider going for coolers with higher CFMs.

There are also window coolers that can be conveniently used to cool a localized room or area. Window-mounted coolers often are ready for installation to be easily installed in vertical or horizontal windows.

The need for regular maintenance

Some units have disclaimers that state that when the evaporator first used there will be an odor that commonly exhausts within a few hours of being turned on. The odor will eventually fade away with the regular and continued use.

Regular cleaning and the proper storage and usage of appliances are main factors to determine their life expectancy and performance.

Thankfully, with evaporative coolers – they require little maintenance overall. The wiping of the device itself, changing of moisture pads, cleaning the pump and draining the water tank are the regular routines to keep your evaporative cooler working well.

Do regular check-ups with the unit as well in case of cracks and leakages that may further harm your coolers.

Don’t forget to ask for the availability for the specific type of your cooling pads when purchasing. It also helps when the evaporative cooler has a built in the water line to simply be able to refill the tank without the hassle of going back and forth a water source to fill it up.

In conclusion

It is important to note that evaporative coolers are not air conditioners. Although they cool as closely as AC’s do compare to electric fans. They are, however, substitutes to air conditioning units. Evaporative coolers are inexpensive options to cooling a certain area, be it indoors or outdoors. Think of it as two electric fans in one with a fair cooling factor. And possibly still have a cheaper energy consumption.

If you have ever been to rooms or spaces that have been cooled with an air conditioner for quite an extended period of time, you are familiar with its style and fatigued effect on the environment.

An evaporator cooler doesn’t produce the same stale effect because it is continuously churning out the fresh breezes from the environment that many people find natural and invigorating.

People in humid areas will likely find that it adds too much moisture to the air, so it is always important to factor in the place you are going to use it.

If you’re not sure if evaporative coolers are the best options for where you are, you can always opt for the smaller and portable ones that are enough for personal cooling – they care the perfect types to go on for a test drive when it comes to investing for your home or workspace’s cooling appliance.

Don’t forget that they do need to be positioned near windows or open doors to also work best.

Portable evaporative coolers, specifically, are good options for a cost-effective way to keep specific spaces cool during the warm days.

A few people when being confronted with the option of having an expensive central air-conditioning system installed in their spaces often end up opting for purchasing several swamp coolers.

In the long run, they are ultimately pleased with the return on their investments in the form of heavily reduced energy costs. Not to mention the mobility it often provides, meaning it can be used in many different rooms as one would opt to.

Now, who doesn’t want the cooling factor while getting to save money, right?
